Note 1: All devices are 100% production tested at TA = +25°C and are guaranteed by design for TA = TMIN to TMAX.
Note 2: Static specifications are tested with the output unloaded.
Note 3: Linearity is guaranteed from codes 115 to 3981.
Note 4: Offset and gain error limit the FSR.
Note 5: Guaranteed by design. Not production tested.
